Hi Abdullah,
We're having more than 8 years of Shopify/Liquid experience. Would love to assist you by developing new custom theme, doing required amount of customization in that, and implementing all other tweaks you are looking for.
Would love to share our portfolio once we get in connection further, so that by analyzing our work you can make a perfect hiring decision.
So, if you prefer we can further discuss this in detail via mail.
My EmailID is - anjani(at)softgrid(dot)in
Best Regards,
Anjani :)
